Manufacturing and workshops

The economics that make this obvious

Every workshop has a list of things that would make a job easier: a fixture so a part stops moving, a guide so a hole goes in the right place every time, a gauge so nobody has to measure, a tray so components stop getting mixed up. Almost none of them get made, because each one is a one-off that would have to be machined or fabricated, and none is individually worth the interruption.

Printing changes the arithmetic. When a fixture costs hours rather than a week and there is no tooling to commit to, the list stops being a list and starts getting done. The saving is not the part — it is the operation the part improves, repeated every day for a year.

It also makes being wrong cheap. Version one of a fixture teaches you something about the operation that nobody knew when it was designed, and version two takes an afternoon.

What gets made

• Workholding and soft jaws shaped to an awkward part, including flexible TPU faces where a finished surface must not be marked.
• Drill guides and location jigs so a repeated operation stops depending on care and attention.
• Assembly fixtures and nests that hold components in position while they are joined.
• Go / no-go gauges and templates for quick checks that do not need an instrument.
• Trays, holders and organisers for kitting, sequencing and stopping mix-ups.
• Guards, covers and dust shrouds for machines whose originals broke and were never replaced.
• Machine spares that are no longer available — see obsolete machine parts.

The full detail on the first several is on the jigs and fixtures page.

What makes a good enquiry

Describe the operation, not the part you have in mind. "We need a bracket" produces a bracket; "the operator has to hold this while drilling two holes and it keeps rotating" produces a fixture that actually solves it, and often a simpler one than the bracket would have been.

A photograph of the workstation is worth a great deal — it shows the clamping, the clearances and the working position that a description never quite captures. And say what the operation runs on, because a fixture for a bench drill and a fixture for a mill are different objects.

What makes a good production aid

Locate, don't fight. The best printed fixtures hold a part in a known position so the operation is repeatable — that is where they transform a job. Clamping and cutting loads belong on steel, and every enquiry gets that assessment before anything is made.

Design for the operator, not the drawing. Fixtures that get used are the ones that load quickly, only go in one way round, and leave the tool a clear path. A round of prototyping normally sorts all three.

Treat them as consumable. A fixture in daily production will wear, and because the model is kept, a replacement is a print rather than a project. That is what makes a printed aid better than a machined one for an operation that will change again next year.

Variants are nearly free. Six versions of a fixture for six different parts is a change to a model and another print, which is the single biggest advantage printing has here.

Where an aid sits near welding or hot parts, or forms part of a machine guard covered by a risk assessment, we flag it at the quote and recommend the right material or process.

Who this suits

Small and medium manufacturers, fabricators, workshops and production teams — anyone with repeated operations and a list of improvements nobody has had time to make. This is naturally recurring work, and it is the kind this workshop is set up for: a settled design, printed again when it wears, revised when the operation changes.

Frequently asked questions

Can a printed fixture hold a part during machining?

It locates a part reliably, which is where a printed fixture transforms an operation. Cutting loads belong on steel, so send the details of the operation and you will get a clear recommendation on which part of the job to print and which to have made another way.

We need six variants of the same fixture. Is that a problem?

It is the opposite of a problem. Variants are nearly free when there is no tooling — a change to the model and another print. This is one of the clearest advantages printing has over any other process for production aids.

What information do you need to quote a jig?

Describe the operation and what goes wrong with it now, send a photo of the workstation, and say what machine or bench it runs on. Those three together are usually enough for a same-day price.

How long does a fixture last in daily production?

It depends entirely on the duty. The practical answer is that it does not need to last forever, because the model is kept and a replacement is a print. Treat a production aid as consumable and the economics work well.

Can you improve a fixture we already have?

Yes. Send the existing one — it is faster to measure and modify something that already half-works than to start from a description of it. That is a reverse engineering job and it is routine.
